摘　　要：为加强废渣再利用辐射环境安全管理,防治放射性污染,本文通过调查黔东南州废渣利用情况,监测废渣放射性水平,验证废渣作为再利用资源的辐射安全性和环保性,分析对环境和公众的影响。调查结果表明,黔东南州当前主要利用的铁渣、铁渣、燃煤炉渣等7种废渣,废渣和其产品的γ辐射水平均满足有关标准,未对周围环境造成一定程度的辐射影响,调查的7种废渣对公众的剂量贡献远小于1mSv/a。To strengthen the management of radiation environmental safety for the reuse of waste slag and prevent radioactive contamination,this paper investigates the utilization of waste slag in Qiandongnan Prefecture,monitors the radioactivity level,and verifies the radiation safety and environmental friendliness of waste slag as a reuse resource.The survey results show that theγradiation levels of the seven types of slag currently used in Qiandongnan Prefecture,such as iron slag,and coal-fired slag,meet the relevant standards,and do not cause a certain degree of radiation impact on the surrounding environment.The dose contribution of these seven types of slag to the public is far less than 1mSv/a.
